问题：

我想要这个功能：开始时只显示scrollingtext1，当您第一次点击Click here时，scrollingtext1将向右移动，scrollingtext2出现，当您第二次点击{{ 1}}，Click here将向右移动，scrollingtext2显示，当您第三次点击scrollingtext3，Click here将向右移动时，{{1}显示，循环继续。

以上是我目前的代码，我被困在这里。谁能帮我这个？感谢。

你走了。

Fiddle

$('.scrollingtext2,.scrollingtext3').hide();

$("#clickme").click(function () {
    var ob = $('li:visible');
    var tw = ob.width();
    var ww = ob.parent().width();
    ob.css({
        left: -tw
    });

    ob.animate({
        left: ww
    }, 2000, 'linear', function () {
        if (!ob.is(':last-child')) {
            ob.next('li').show().css('left', -tw);
            ob.hide();
        } else {
            ob.parent().find('li:first').show().css('left', -tw);
            ob.hide()
        }
    });
});

或

$('.scrollingtext2,.scrollingtext3').hide();

$("#clickme").click(function () {
    var ob = $('li:visible');
    var tw = ob.width();
    var ww = ob.parent().width();
    ob.css({
        left: -tw
    });

    ob.animate({
        left: ww
    }, 2000, 'linear', function () {
        if (!ob.is(':last-child')) {
            ob.next('li').show().css('left', 0);
            ob.hide();
        } else {
            ob.parent().find('li:first').show().css('left', 0);
            ob.hide()
        }
    });
});

如果您希望在再次点击之前显示下一行

您的HTML也有语法错误，因此将其更改为

<div class="jp-title">
    <ul>
        <li class="scrollingtext1">scrolling text1: scrolling text1 scrolling text1 scrolling text1 scrolling text1</li>
        <li class="scrollingtext2">scrolling text2: scrolling text2 scrolling text2 scrolling text2 scrolling text2</li>
        <li class="scrollingtext3">scrolling text3: scrolling text3 scrolling text3 scrolling text3 scrolling text3</li>
    </ul>
</div>
<div id="clickme">Click here</div>

从css中删除visibility: hidden，以便我们可以使用jQuery中的选择器告知可见的li

.scrollingtext2, .scrollingtext3 {
    position:absolute;
    white-space:nowrap;
    font-family:'Trebuchet MS', Arial;
    font-size:18px;
    font-weight:bold;
    color:#000000;
}
